NURU-KAN: Umami-Packed Drinking Enjoyment

Drinking Nuru-Kan warmed Sake during the wintertime has existed from back in the 8th century among the upper echelon of Japanese society. By the 16th century, this practice gradually spread through other communities, and Nuru-Kan, once relished exclusively during the cold seasons came to be enjoyed all year round. Following the culmination of what was considered the golden age for warmed Sake from late 19th century to the first half of the 20th, paved way to today’s modern trend of Tanrei Karakuchi, light & dry, Sake. Regardless, Nuru-Kan has been steadfast and is making a gradual comeback at today’s eateries and in homes.

Japanese restaurants in the US typically have two types of Sake drinking followers: (1) guests who order the house hot Sake, and (2) those who order the premium Ginjo-type, served chilled. It’s interesting to note that these preferences correlate with how much Sake drinking is entrenched in a particular regional area. Though cold Ginjo Sake is sought after in cosmopolitan cities, hot Sake remains the favorite in the less urban areas. And while oftentimes hot Sake is served at over 149+ degrees F, that kind of heating pretty much destroys the delicate flavors that Sake has to offer.

With such a wide array of Sake types currently available, it’s prime time to offer American Sake fans Nuru-Kan, warmed Sake, to highlight a more mellow, Umami-filled drinking experience.

Nuru-Kan warmed Sake, served 95˚F to 122˚F, is ideal for highlighting certain flavors and Sake types.

Sake Flavor Characteristics by Serving Temperature

Selecting Sake Best for Nurukan

Sake Suitable for Nuru-kan

  • Sake With Acidity
    Sake with sharp acidity at room temp. Warming this type of Sake emphasizes the sweetness and balances out the acidity.
  • Sake With Umami Component
    Kimoto and Yamahai Sake types packed with amino acids, the Umami component. Warming these types accentuates flavor and increases Umami.
  • Aged Sake
    Aged Sake with melting caramel aroma such as Shukoshu. Warming this type of Sake enhances other aromas while tapering off pungent aromas.

Sake Not Suitable for Nuru-kan

  • Aromatic Sake
    Warming Ginjo type Sake over intensifies the aroma, which disrupts the flavor of the food.
  • Fruity & Sweet Sake
    Warming Sake brewed specifically to be sweet will only further exaggerate its sweetness.
  • Sake with Off Aroma
    Warming Sake with off aromas, such as turpentine, paper, wood/pulp material, will further accentuate the unpleasant smell.
